The single-person double-blowing air shower is installed at the entrance of the clean area. Through double-sided nozzles and filtered circulating air, the surface of the clothes of the entering personnel is blown and sprayed to reduce the particles brought in by the personnel. Aili Industrial configures the air shower size, nozzle layout, filtration system and control functions based on the installation space, traffic flow, access interlocking and material requirements, so that the personnel entry and exit process matches the clean room entrance management.

The air shower room is equipped with nozzles on both sides to spray the surface of people's clothing from different angles. Compared with single-sided blowing shower, double-sided blowing shower has wider coverage, which helps to reduce the blind zone of blowing and showering when personnel turn around.
The number, angle and air outlet speed of the nozzles can be configured according to the size and traffic requirements of the air shower room. After entering, personnel should turn their bodies in the shower area so that all surfaces can be covered by the airflow. Air shower room classification and structural form can be viewed Air showers understand different models.
After the air passes through the primary filter and high-efficiency filter, it is sent to the nozzle by the fan, blows the surface of the personnel, and then returns to the front end of the filtration system through the return air outlet to form a cycle.
Return air filtration needs to be matched with the nozzle layout, air duct and fan working point. The return air outlet should be kept clear to prevent obstruction by clothing or objects from affecting circulation. For specific air volume calculations, please refer to How to convert face wind speed and air volume?。
The air shower room is usually equipped with induction control, which automatically starts the shower after personnel enter. The front and rear doors are interlocked to prevent the doors on both sides from being opened at the same time and causing an airflow short circuit.
The blowing time can be set according to management requirements, usually between a few seconds and tens of seconds. The access interlock and shower logic should match the personnel entry and exit process to avoid low traffic efficiency or interlock failure.
The air shower box can be made of stainless steel or steel plate with plastic spray material, which shall be confirmed according to the use environment, cleaning requirements and appearance requirements. Stainless steel is corrosion-resistant and easy to clean, making it suitable for places with high surface cleaning requirements.
The inner wall should be smooth, not prone to dust accumulation, and easy to wipe daily. In places that require frequent cleaning, attention should be paid to corner treatment and sealing structures to reduce cleaning dead corners.
The air shower room can be configured with lighting and status displays to indicate that the air shower is in progress or that access is allowed. Lighting should meet internal operation and inspection needs, and status display should be easy for personnel to identify.
If the project needs to be linked with the access control system or upper-level system, the control interface and communication protocol should be confirmed during the design stage.
After people enter the air shower room, the induction device triggers the fan to start. After primary filtration, the air is sent to the high-efficiency filter by the fan, and then blown to the surface of the personnel through the nozzles on both sides. The air carrying particles returns to the front end of the filtration system through the return air outlet, forming a cycle.
Personnel enters → Induction start → Primary filter → Fan air supply → High efficiency filter → Double-sided nozzle blowing → Return air circulation → End of blowing → Unlock the exit door
The blowing time and nozzle angle need to be confirmed based on the actual traffic flow. People's clothing, carrying items and standing position may affect the shower effect, and should be verified according to the agreed conditions after installation.

The air shower is mainly used for surface blowing of personnel and clean area entrance management. It does not replace the dressing process, material purification and the air purification system of the clean room itself. When infectious or hazardous materials are involved, equipment should be selected based on the risk.
The air shower requires installation space, front and rear traffic directions and door opening space. Before installation, the size of the door opening, floor flatness and surrounding passages should be checked to confirm that the air shower can be installed and used normally.
The shower time should match the personnel traffic efficiency. If the time is too short, the shower may be insufficient, and if the time is too long, traffic may be affected. Access control interlock logic should be consistent with the changing process and clean area management requirements.
Return air vents and filters require regular maintenance, and the installation location should be convenient for replacement and maintenance. Maintenance channels should be reserved around the air shower to prevent the equipment from being blocked by other objects. Insufficient maintenance channels will increase subsequent expenditures. This is reflected in what later expenses will be increased due to insufficient maintenance channels . There is a more detailed analysis of
The cabinet material and surface treatment should match the cleaning procedures and use environment. Stainless steel material is suitable for places with high surface cleaning requirements. Plastic spraying of steel plates can be confirmed according to project requirements.
Clean the inner wall, nozzles and return air outlets of the air shower in accordance with management requirements to avoid dust accumulation that affects the shower effect. Pay attention to protecting the nozzle angle and filter system seal when cleaning.
Maintain the primary filter according to the frequency of use and environment, and determine the maintenance needs of the high-efficiency filter based on pressure difference, wind speed and filter status. After replacement, the installation seal and related performance should be rechecked.
Regularly check access control interlocks, induction devices and shower timing functions to ensure normal access procedures.
Aili Industrial has a manufacturing base of approximately 30,000 square meters, covering R&D and manufacturing links such as motors, fans, control systems, sheet metal, air filters, and complete machine assembly.
For a single-person double-blowing air shower project, the box size, nozzle layout, filter configuration, fan working point and control function can be checked together to support standard selection, non-standard design and batch project matching.

Double-blowing air showers have nozzles on both sides for wider coverage; single-blowing air showers usually have nozzles on one side. The selection should be based on the direction of personnel traffic, shower requirements and installation space.
It is necessary to check the air shower exterior dimensions, front and rear door opening spaces and maintenance access. Before installation, the on-site door opening, ground and surrounding access conditions should be confirmed.
The blowing time is usually adjustable, and the specific range is confirmed according to the control plan. The set value should match the personnel traffic efficiency and clean area management requirements.
The access control interlock is a configuration that prevents the doors on both sides from being opened at the same time. It should be used according to management requirements and is not recommended to be closed. The specific logic is confirmed in the control scheme.
It should be judged based on the pressure difference, wind speed and filter status. Recheck sealing and related performance after replacement.
Clarifying the installation space, traffic direction, personnel flow, shower requirements and material requirements will help determine the air shower configuration suitable for the clean room entrance.
